title: Lactobacillus plantarum 29 inhibits Penicillium spp. involved in the spoilage of black truffles (Tuber aestivum).
abstract: The effect of an antifungal culture of Lactobacillus plantarum to be used in the storage at refrigeration temperature of fresh black truffles was examined. The strain was selected among 29 lactobacilli isolated from foods and evaluated for their viability and acidification activity at 4 °C, as well as for their inhibitory activity against 11 Penicillium strains isolated from truffles stored at refrigeration temperature. Lb. plantarum 29 showed the ability to hold not only the growth of Penicillium isolated from truffles, but also that of P. digitatum DSM 2750, a green mold involved in the spoilage of truffles. The antifungal activity was observed in vitro and in situ, and the sensory characteristics of truffles were preserved during the cold storage.
